Intruder Selfie™ is a photo-based app that allows you to see photos of intruders who have tried to access your device without your permission. If you are the victim of theft or fraud, you can use this app to quickly see if your phone has been compromised.
This app uses a simple mechanism that automatically takes a photo when somebody tries to unlock your device with an incorrect password. You will be able to know who has done this without you being aware of it.
You will need to enable the Device Administrator permission for this app to work. This permission lets the app detect failed unlocking attempts on your device.
